I'll check the USB loaders out since the backup loaders I've used so far does not have the hook type OSSleepThread (apparently necessary for Call of Duty).
I'm surprised no publisher has never said anything regarding Wii piracy or perhaps this is because its no PSP. Is there even possible for them to come up with a work around?
On a related note I followed this, the 3.1-3.4 Twilight/Downgrade/Gamma Tutorial, but I always get a black screen for the Shop Channel and it takes me nowhere. :/
